Gen2 is 2014-now and while the biggest differences are the colors of paint, Yamaha has slipped in some items that you will only find by looking at part numbers for being superseded.

I think starting with the 2017, they are Euro 4 compliant and you need some kind of OBD II adapter cable to read and erase error codes. The 2015 still has access to erase codes via the instrument panel buttons. Otherwise no feature or equipment differences outside of color & graphics.

I guess until 2016 the ST is EURO 3 in Europe, In fact, since 2017 the model has change some parts like the cat and emission control.
In my opinion, the response of the bike at low rpm is different between 2017 and 2016, In addition to this, I guess the 2016 model is better than the 2017 and 2018.
Other parts that has been changed in 2019 are the rims, now are stronger than before, In fact they have a new part number.

Didn't I see a report on slightly more robust rim(s) on a later model? Something Yamaha said nothing about.

I do think that you are correct about throttle response. I've only ridden a/my '17, but I've read about low rpm sluggishness in previous model years. I know that my '17 has no sluggishness anywhere in the rpm range, and runs like a scalded ass ape. MY opinion is that it's another undocumented change/improvement; like the rims. "Better" is in the eyes of the beholder, but I think that the '17 is better than the '16. (based on what I've read)

I'd like to learn more about this. Are the wheels observably different? Manufacturers will change the part number if the part is just a different color, of if the part is sourced from a different supplier, so a new P/N doesn't necessarily mean there's anything physically different.

Thanks guys! I guess if I end up with a '15 model and the throttle feels sluggish to me, I think I can have the ECU reflashed to cure that. I like the fact that the '14's, 15's and '16's are an earlier OBD version. There are no Yamaha motorcycle dealers within 100 miles or so of me that have competent service shops (so I've been told), so I'm on my own for maintenance and even recommended dealer service work unless I go a couple hundred miles and spend the night while my bike is in the shop.

Regardless of year, the engine is a very straight forward Japanese mill.

Its an S10. I wouldn’t worry about too many trips to the dealer. Easiest bike I’ve ever owned!

Well guys, I ended up finding and buying a spotless '16 ES with 7500 miles on it. It was in Pennsylvania, but I put down a deposit on it, hitched up my trailer, and a buddy and I hauled butt from northern MO to SW PA and nabbed it. Waynesburg Yamaha in Waynesburg, PA was terrific to work with. They had it all serviced (including spoke torque) and shined and we were in and out of there in about an hour.

I absolutely LOVE the bike. A sluggish throttle is the last thing to worry about on this bike. In fact, even in tour mode it's quite twitchy. I'm having to get used to it, and the engine braking is lots more than I've been used to, but I'm learning it's habits quickly. For now, I don't think I'm going to mess with the ECU.

Have any of you ever put a G2 Throttle Tamer on an S10? Their ads make it look like a sound approach to taking some of the twitch out of it.

I just got home with the bike on Sunday morning and have only put about 250 miles on it so far, so I haven't riden it nearly to develop muscle memory for it, and to become used to the fuel injection vs. the carburetors on my old Concours.

Congratulations and welcome to the family.

A flash will do the same as a throttle tamer and a LOT more, and you can do it for a reasonable price. I'd suggest putting a thousand miles on first at least. These bikes really take close to 5,000 miles to really break in. Do a search for more info on flashing the ECU memory, and break-in, and the other usual noob topics.
